ATTAcHMENT FOR INK-BOTTLES.

Specification of Letters Patent.

Patented Decv 3, 1907.

Application filed January 28. 1907- $erial No. 354.540.

To all whom it may concern:

Be it known that I, EDWIN M. OAsE, citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Attachments for Ink-Bottles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in ink-bottle attachments; and it consists in the novel construction of device more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is an elevation of a conventional ink bottle having my attachment inserted thereinto, Fig. 2 is a to plan of Fig. 1, the pen holder being omitte Fig. 3 is a vertical section on line- 33 of Fig. 2 Fig. 4 is a horizontal section on line 14 ofFig. 3; Fig. 5 is a sectional detail showing the application of the adjustable cup or diaphragm into the casing or shell; and Fig. 6 is an elevation (partly broken) of the casing or shell intended to be inserted into the bottle.

The object of my invention is to provide means for preventing the dipping of a pen to undue depths into the contents of an inkbottle (or inkwell), the device being intended to limit the dipping to a depth only sufficient to supply the pen with the necessary quantity of writing fluid. The attachment thus insures against wetting the pen holder and soiling the fingers of the writer, all as will herein more fully appear from a detailed description of the invention which is as follows:

Referring to the drawing B, represents an ordinary ink-bottle of commerce having the usual neck n. -Insertible into the bottle,

through the neck thereof is a tubular shell or casing 1 having a screw-thread struck alpng the length thereof, the said casing being adapted to receive a screw-threaded cup 2 having perforations 0, o in the bottom thereof, and upper terminal inwardly deflected prongs or lugs 3 which serve as bearings or abutments for a blade or other instrument 0 inserted into the cup (Fig. 2), for purposes of driving the cup into the casing. By turning the blade 0 in Fig. 2 to the right, it is obvious that the cup will be screwed into the casing, to any required depth. The cup 2 however need not be inserted into the casing until after the latter has been passed into the bottle. The bottom of the casing 1 has excised from the walls thereof a series of tongues or arms a, a, of a length such as to permit the ends of the arms to frictionally engage the walls of the body of the bottle (Fig. 4) when said arms are, forced outwardly and downwardly. The casing 1 being passed into the bottle B, a rod t is inserted into the casing, and into the slits 8 left by the cutting of the tongues a, and the latter are forced outwardly against the walls of the bottle (Figs. 4 6). i

j The casing is of a length sufficient to reach a trifle beyond the base of the neck a. Near the top there are excised from the casing body a series of prongs l), b, leaving slits 8 through which a suitable tool may be in- I serted, and the prongs bent up against the base of the neck a by a pressure of the tool against the prongs, and in Fig. 3 I show a tool t in position to effect a partial bending,

of the prongs in the desired direction. Of course to bend the prongs well up against the base of the neck, a tool of special design would have to be improvised, depending on the length of the neck of the bottle into which it is inserted. This arrangement serves to secure the casing in position within the bottle, the ink i being free to flow into the casing as is obvious. The depth to which the pen at the end of the pen holder P can be inserted into the ink will be governed by the depth to which the cup 2 has been driven into the casing. The perforated bottom of the cup which acts as a diaphragm, arrests the pen so that it can be submerged in the ink just so far and no farther. In this way there is no danger of taking up more ink than is necessary, and as the writing fluid is used up, the diaphragm 2 can be correspondingly lowered as is obvious.

Having described my invention. what I claim is:

1. As an article of manufacture, a shell or casing insertible into an ink-bottle and provided with means for engaging the walls of the body of the bottle to avoid lateral dis: placement of said shell, and with means for engaging the neck of the bottle for the support of the upper portion of the shell, a cup having a perforated bottom serving as a diaphragm, insertible into the casing and adjustable along the length thereof for limiting the depth of insertion of the pen thereinto, substantially as set forth.

2; As an article of manufacture, a screwthreaded shell or casing insertible into an ink-bottle, and having a series of tongues or arms excised from the Wall thereof adapted to be bent against the body portion of the bottle, and having a series of prongs excised therefrom adapted to be bent against the base of the neck of the bottle, a screwthreaded cup having a perforated bottom serving as a diaphragm, insertible into the casing and adjustable along the length there- 10 of for limiting the depth of insertion of the pen thereinto, substantially as set forth.

In testimony whereof I affix my signature, in presence of two Witnesses.
